Abstract/Description:
We report high resolution Compton scattering measurements on an Al97Li3 disordered alloy single crystal for momentum transfer along the [100], [110] and [111] symmetry directions. The results are interpreted via corresponding KKR-CPA (Korringa-Kohn Rostoker coherent potential approximation) first principles computations. By comparing spectra for Al97Li3 and Al, we show that the momentum density in the alloy differs significantly from the predictions of the conventional Fermi liquid picture and that the ground state of Al is modified anomalously by the addition of Li.
